RAIL-FASTENING nnvron.

Application filed March 25, 1919.

To all whom it may concern:

Be it known that I, DIRK Annmns Tmven, a Netherlands subject, residing at 75 O0- kcrse street, Krugersdorp, Transvaal, Province of the Union of South Africa, have invented certain new and useful Improvements in Rail-Fastening Devices, of which the following is a specification.

The present invention relates to rail fastening devices combined with sleepers. The object of the invention is to provide a simple and efficient fastening which has no screws or like parts liable to be rendered useless by rust.

In the accompanying drawings Figure I is a perspective view of a sleeper embodying the invention.

Fig. IT is a vertical section, and

Fig. 111 is a similar view showing the method of operation.

1 is a sleeper which may be of pressed metal. 011 it are formed clips 2 for en gaging the inner side of the base 3 of the rails 4-. Said clips may conveniently be pressed up from the body of the sleeper in the known manner. 5 indicates tie bars one of which is provided for each rail l. Said tie bar extends longitudinally of and beneath the sleeper. Its outer end is formed with a reversely hooked end 6 forming with the bar itself, a jaw which engages the outer side of the base 3 of the rail and the part 7 of the sleeper beneath said base. The sleeper is cut away at 8 to permit the hook 6 to be passed into position from below.

To look the hook 6 on the rail the other end ofthe tie bar 5 is turned up at 9 to form a shoulder directed oppositely to the hook 6. Said upturned end is passed into an aperture 10 in the sleeper, the edge 11 of which forms a complementary shoulder to the part 9 and holds the tie bar against 0utward movement with respect to the rail.

The bent up end is suitably retained in place, and for that purpose it may be bent again horizontally as at 12 and engaged by a wooden block 13, passed between such ends 12 of both the tie bars and the surface of the sleeper. In order to lock the block in place it is slightly wedge-shaped and the surface of the sleeper is'formed with teeth 14: directed against the withdrawing movement of the wedge. The hooked end 6 is sloped upward to correspond with the upward slope of the base of the rail, so that Specification of Letters Patent. Patented Aug. 31, 1920.

the jaw between the said hooked end and the adjacent part of the tie bar is tapered. The result is that upon said" hooked end being forced laterally onto the base of the rail it both holds the rail against lateral movement and also forces the rail down into firm contact with the sleeper.

In making use of the invention the rails 4 are passed into the fixed clips 2. A tie bar 5 is then passed through the aperture 10 completely under the sleeper and its hooked end 6 is passed up through the opening 8 and into engagement with the base of the rail, as indicated in Fig. 111. The upward slope of the hook 6 facilitates such engagement of the hook with the rail notwithstanding that the tie bar stands at an angle with the sleeper. The tie bar for the other rail being similarly inserted, the tie bars are forced inward, for instance by driving a drift into the opening 8 until the bent-up ends 9 can be broughtup through the aperture 10 and be caused to engage the edges 11 thereof. The block 13 is then knocked into place. To release the rails, the block 13 is knocked out of place and the ends 9 of the tie bars are forced down "and out of the aperture 10.

I claim:

1. A hollow sleeper provided with means toward each end for engaging the inner sides of the bases of rails carried by the sleeper and formed with a central aperture, a tie bar for each rail having a hooked end engaging the outer side of the base of the rail and the underlying part of the sleeper, each of said tie bars having the other end turned upward and engaged in the aperture in the sleeper.

2. A hollow sleeper provided with means for engaging one side of the base of a rail, an opening in the sleeper adjacent the other side of the base of the rail, a tie bar formed with a hooked end passed up through said opening and engaging-the base of the rail and the underlying part of the sleeper, the other end of said tie bar being turned first upward and then horizontally, the sleeper being formed with an aperture in which said upturned end is engaged to lock the hook on the rail, and a block inserted be tween the horizontally turned end of the tie bar and the surface of the sleeper.

3. A hollow sleeper provided with means toward each end for engaging the inner sides of the bases of rails carried by a sleeper and formed W1th a central aperture, a tle bar for each rall havlng a hooked end engaging, the outer side of the base of the rail and the underlying part of the sleeper, each'of sald tle bars havlng the other end turned upward and engaged 1n DIRK ANDRIES TENGE.
